It is important that you clean your computer periodically to ensure that it will function properly and have a long life. When you clean your computer you not only improve the physical appearance, but you also prolong the life of the computer.
The cleanliness of a computer says something about the user. When students and other faculty and staff see a dirty computer, they immediately get a sense of unprofessionalism. On the contrary, a clean computer will clearly say expertise.
If that’s not enough to convince you to clean your computer, think about this: The computer keyboard is often the most germ infected item in your home or office; often, it will contain more bacteria than your toilet seat. Cleaning it can help remove any dangerous bacteria.
Generally you should try to clean your computer every 3-6 months.
